Analytic study of dark photon and gravitational wave production from axion
Abstract Axion-like fields heavier than about 10 −27 eV are expected to oscillate in the radiation dominated epoch when the Hubble parameter drops below their mass. Considering the Chern-Simons coupling with a dark gauge boson, large amount of dark photons are produced during a short time interval t...
